Detailed Description

USGS Hawaiian Volcano Observatory scientists Frank Younger and Patricia Nadeau talk about sampling the water at the bottom of Halemaʻumaʻu, a crater at the summit of Kīlauea Volcano. The water appeared in July 2019 and has steadily risen since then. On October 26, 2019, an unoccupied aerial system (UAS) was used to collect a sample of the water to investigate its source and composition. Limited UAS flights into the Kīlauea summit area are conducted with permission and coordination with Hawai‘i Volcanoes National Park. The information is used to assess hazards at Kīlauea's summit, and is shared with the National Park Service and emergency managers.
